Commercial Gate Installation & Automation in Atlanta, Georgia

Apex Fence Company installs commercial gates and automation systems for industrial facilities, corporate campuses, multifamily developments, municipalities, and general contractors throughout metro Atlanta. A commercial gate is the most mechanically complex component of any fencing system — the structure that every vehicle, employee, and delivery cycles through, potentially hundreds of times a day, under full operator load and weather exposure. The post engineering, gate frame construction, operator selection, access control integration, and safety device compliance all have to be specified correctly before installation begins. Getting one component wrong produces failure that affects the entire access point. Apex has been engineering and installing commercial gates across Cherokee, Cobb, Fulton, Gwinnett, Bartow, and Forsyth counties since 2005, on projects that range from single automated vehicle gates on industrial lots to multi-entry access control systems on corporate campuses.

Commercial gate failure is not a fence problem — it is an operations problem. A slide gate that derails, an operator that fails under cycle load, a gate post that develops lean from an undersized footing: any one of those failures shuts down vehicle access to a facility until it is repaired. The companies and project managers who have experienced that understand what it means to specify and install commercial gates correctly the first time. Apex runs commercial gate installations across the full range of facility types in metro Atlanta, and the failure modes our crews are trained to prevent are the ones we have seen firsthand on commercial sites — not the ones described in a manufacturer training video.

General contractors and facility managers working with Apex get a single-scope subcontractor for gate structure, operator, access control, and safety devices. We do not install the gate and hand off the operator to an electrical subcontractor who is not familiar with the gate geometry. The components of a commercial gate system interact — operator torque rating against gate weight and wind load, loop detector placement relative to gate travel, safety edge mounting relative to the gate’s latch point — and a crew that installs the full system understands those interactions in a way that a split scope does not. Every commercial gate installation carries a 5-year workmanship warranty. Operator and access control components carry manufacturer warranties coordinated at closeout.

Commercial gate configuration is determined by opening width, available clearance, cycle frequency, gate material, security requirements, and site geometry. The right answer is site-specific. Here is how Apex approaches the primary commercial gate types and automation systems across the applications most common in metro Atlanta.

Cantilever Slide Gates

The standard vehicle gate specification on commercial and industrial sites throughout metro Atlanta. Cantilever slide gates are supported entirely by roller carriages mounted to a counterbalanced frame — no bottom track in the driveway surface. That distinction matters on commercial sites where forklift traffic, heavy truck tires, and high-cycle use would damage or obstruct a track-driven system within months of installation. What determines whether a cantilever slide gate performs correctly over its service life:

• Counterbalance ratio: A cantilever gate requires a counterbalance section behind the gate post equal to approximately one-third of the gate’s opening width. On sites where that clearance is constrained, the counterbalance geometry has to be engineered rather than defaulted — a gate without adequate counterbalance places asymmetric load on the roller carriages that accelerates wear and produces lateral drift over time
• Roller carriage specification: Roller carriages are rated by gate weight. A 20-foot ornamental steel cantilever gate and a 20-foot chain link cantilever gate are not the same weight, and the roller carriage specification for each is different. Installing residential-duty carriages on a heavy commercial gate is one of the most common sources of premature gate system failure on commercial sites
• Gate frame construction: Commercial cantilever slide gate frames are fabricated from structural steel tube — 2-inch or 2.5-inch square on standard applications, heavier on wide or heavy gates. The horizontal truss structure of a cantilever frame has to be rigid enough to prevent the gate from sagging at the latch end as the frame ages under cyclic load
• Operator foundation: The slide gate operator is anchored to a concrete pad adjacent to the gate post. Pad dimensions, anchor bolt pattern, and concrete depth are specified by the operator manufacturer — field-poured pads that deviate from the operator’s mounting specification produce vibration, anchor bolt stress, and accelerated operator failure

Track-Driven Slide Gates

Track-driven slide gates operate on a bottom rail set in or adjacent to the driveway surface. Lower initial cost than cantilever systems and appropriate on applications where driveway surface integrity is not a concern and vehicle traffic is light enough that track obstruction and damage are not operational issues. Specific applications where track-driven gates are the correct specification:

• Pedestrian and light vehicle access gates where forklift and heavy truck traffic is absent
• Secondary access gates on industrial sites where the primary vehicle gate is cantilever and the secondary opening sees lower cycle frequency
• Applications where the available fence line clearance for a cantilever counterbalance section is genuinely insufficient and the site geometry cannot accommodate a cantilever configuration

Track maintenance — debris removal, track alignment, drive wheel inspection — is an ongoing operational requirement on track-driven gates that cantilever systems eliminate. On high-cycle commercial sites, the operational maintenance burden of a track system is a real cost that the initial price difference does not offset over the gate’s service life.

Swing Gates

Swing gates on commercial applications are appropriate where the driveway has sufficient depth behind the gate for full swing clearance and the opening width does not exceed what a single or paired leaf can handle without creating gate post load problems. Commercial swing gates differ from residential swing gates primarily in frame weight, post specification, and hinge engineering:

• Commercial swing gate posts are set in concrete footings engineered for the gate’s weight and swing arm load — not sized from the adjacent fence line post specification. A 16-foot double-leaf swing gate places substantially more load on the hinge posts than the fence line carries, and the post and footing design reflects that
• Bi-fold swing gates — two-leaf gates that fold in the center on opening — are the correct configuration on commercial applications where swing clearance is limited but a slide gate is not feasible. The folding geometry reduces the required clearance depth by half while maintaining the full opening width
• Vertical pivot lift gates are a commercial swing gate variant for extremely constrained clearance conditions — the gate lifts vertically rather than swinging, requiring minimal lateral clearance at the cost of vertical clearance requirements and more complex operator engineering

Commercial Gate Operators

Gate operator selection on commercial applications is an engineering decision, not a catalog selection. The operator has to be specified against the gate’s weight, the site’s cycle frequency, the power supply available, and the duty cycle rating appropriate to the application. Getting this wrong produces premature operator failure — often within one to two years on a high-cycle commercial site where a residential-duty operator was installed to reduce initial cost:

• Duty cycle rating: Commercial gate operators are classified by duty cycle — the percentage of time the operator can run continuously before requiring a cool-down period. Standard duty is appropriate for low-cycle secondary gates; heavy duty for primary vehicle gates on active commercial sites; continuous duty for high-cycle applications like parking structures and transit facilities where the gate cycles multiple times per hour throughout the operating day
• Operator torque and force ratings: The operator’s torque output (for swing gates) or linear force (for slide gates) must be matched to the gate’s weight and any wind load the site experiences. An undersized operator that runs near its torque limit on every cycle fails faster and produces incomplete gate travel in adverse conditions
• Power supply: Commercial operators are available in 110V single-phase, 220V single-phase, and 220V three-phase configurations. Three-phase power is the preferred specification on continuous-duty commercial operators for the efficiency and torque characteristics it provides. Solar-powered operators are appropriate on remote sites without reliable grid power; battery backup is standard on all commercial operator configurations for power outage continuity
• Operator brands: Apex installs operators from established commercial automation manufacturers — LiftMaster, FAAC, Linear, and HySecurity among them. Operator selection is driven by the application requirements, parts availability in the Atlanta market for ongoing service, and the manufacturer’s commercial warranty terms. We do not specify operators based on margin

Access Control Systems

Access control on commercial gate installations ranges from a keypad and remote transmitter on a light commercial application to a fully integrated system tied to the facility’s security management platform on a corporate campus or federal facility. Apex installs access control components as part of the gate scope — not as a separate handoff to a security integrator who is unfamiliar with the gate geometry:

• Keypad & proximity card readers: The standard access control specification on industrial and light commercial applications. Keypad entry for secondary users, proximity card or fob for primary access, with programmable access levels and audit logging depending on the controller specification
• Telephone entry systems: Common on multifamily developments and commercial properties where visitor management — rather than employee access control — is the primary function. Telephone entry systems allow visitors to call specific units or departments and be granted access remotely without a staffed gate attendant
• Loop detectors: Inductive loop detectors embedded in the driveway surface trigger gate opening for approaching vehicles and prevent the gate from closing on a vehicle in the opening. Loop placement relative to gate travel and vehicle approach geometry is a field engineering decision — loops placed incorrectly produce nuisance triggers or fail to detect vehicles reliably
  License plate recognition (LPR): Increasingly specified on corporate campuses, logistics facilities, and high-security commercial applications where vehicle identification is a security or operational requirement. LPR camera mounting is coordinated with the gate structure during installation rather than added after the fact
• Integration with facility security systems: On corporate campus and institutional applications, the gate access control system integrates with the facility’s broader security management platform — badging system, CCTV, alarm system, visitor management. Apex coordinates the gate and operator installation with the security system integrator and provides the infrastructure provisions their system requires

UL 325 Safety Compliance

• UL 325 is the safety standard for automated gates in the United States and is not optional on any commercial gate installation. The standard requires specific entrapment protection devices based on gate type and installation location — devices that prevent the gate from closing on a person or vehicle that is in the gate’s travel path:
• Photo eye sensors across the gate opening detect obstruction in the gate’s path and reverse or stop gate travel on detection
• Contact-sensing safety edges on the gate’s leading edge detect physical contact with an obstruction and stop gate travel immediately
• Loop detectors in the gate’s path provide vehicle presence sensing that prevents gate closure on a vehicle that has not cleared the opening
• Warning signs, warning lights, and audible alerts are required at specific locations relative to the gate as part of UL 325 compliance

Apex includes UL 325-compliant safety devices on every automated commercial gate installation. These are not optional add-ons on a commercial gate — they are code-required safety components, and a gate installation that omits them creates liability exposure for the property owner that no cost reduction justifies.
